Vim li cas 316 stainless hlau yeeb ntxig kim dua 304?

Hauv lub neej txhua hnub, stainless hlau kav yog ntau dua, nrog ntau cov ntaub ntawv siv rau lawv ntau lawm. Qee cov kav dej yog tsim los ntawm 304 stainless hlau, thaum lwm tus siv 316 stainless hlau. Ib lo lus nug nquag yog: uas kim dua, 304 stainless hlau yeeb nkab lossis 316 stainless hlau yeeb nkab? Cia kuv piav txog qhov sib txawv ntawm ob.

Qhov ceev ntawm 304 stainless hlau yeeb nkab yog 7.93g / ㎝³, thaum lub ntom ntom ntawm 316 stainless hlau seamless yeeb yog 8. Hauv cov ntsiab lus, tsis muaj qhov sib txawv ntawm ob, raws li ob leeg yog ib feem ntawm tsev neeg dav dav ntawm cov hlau tsis muaj hlau. Lawv faib cov yam ntxwv xws li acid tsis kam, alkali tsis kam, yooj yim ntawm kev ua, thiab kev nruj. Txawm li cas los xij, yog tias peb delve ntxaum, qhov sib txawv ntawm ob yam khoom tau ua pom meej.

Daim ntawv thov sib txawv:
304 Precision stainless hlau yeeb muaj ntau cov kev siv thiab yog paub rau nws cov zoo corrosion tsis kam. Nws yog ib qho muaj feem ntau siv nyob rau hauv cov khoom lag luam zoo li cov khoom lag luam tiv thaiv tub sab, tus saib ntaiv, anti-tub sab lub qhov rooj, khoom siv tsheb nres tsheb, thiab khoom siv kho mob.
316 Cov yeeb nkab stainless hlau muaj ntxiv cov ntsiab lus xws li ni, cr, thiab mo piv thiab ua kom muaj zog dua thiab ua kom haum corrosion thiab kub ua tsis kam. Raws li qhov tshwm sim, nws yog qhov tsim nyog rau siv nyob rau hauv ib puag ncig cov khoom siv, kev lag luam dej, zas

Tshuaj lom neeg tshuaj lom neeg thiab kev sib piv ua tau zoo:
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm 3 {0 4 stainless hlau yeeb nkab hlau yog 06cr19NI10, thiab rau 316CR17NI2NI. Tus "06" qhia tau cov ntsiab lus carbon tsawg dua 0.08%. Qhov "CR19" txhais tau tias 19% chromium, thiab "NI10" yog hais txog 10% npib tsib.
Lub ntsiab tseem ceeb rau stainless hlau ib xeb thiab corrosion tsis kam yog npib tsib xee, uas yog kim kim. Thaum ob qho tib si 304 thiab 316 stainless hlau muaj npib tsib xee, thiab tseem suav nrog Molybdenum (mo), tshwj xeeb yog ua kom corrosion, tshwj xeeb tshaj yog nyob hauv chloride ib puag ncig. Raws li qhov tshwm sim, 316 stainless hlau yog ntau xeb-resistant thiab, yog li ntawd, ntau dua li 304 stainless hlau.

Xaiv cov khoom siv yog:

Ob hom stainless hlau muaj cov ntawv thov sib txawv raws li lawv cov peev txheej. Nws yog ib qho tseem ceeb kom xaiv cov yeeb nkab tsim nyog steel hlau raws li cov kev xav tau ntawm koj ib puag ncig. Piv txwv li, hauv thaj chaw qhuav, 304 Austenitic alloy steel yeeb nkab feem ntau yog vim lawv zoo corroscion tsis kam thiab tsawg tsawg txoj kev xeb. Txawm li cas los xij, nyob rau hauv cov ntug dej hiav txwv lossis ib puag ncig uas muaj rau cov nroj tsuag muaj xeb, 316 Stainless kho cov yeeb nkab yog qhov kev xaiv zoo dua vim yog lawv zoo tshaj rau kev xeb.
